lightanother,
by the way, if you update to 0.92, which contains my no-brainer:P bugfix, it'll do what this contribution was origianlly written to do:
1) for incomplete orders, everything will still be logged with the status showing "PayPal Processing"
2) for completed orders, the status will become "Pending" and emails will be sent.
as for dropped orders, everything will still be logged with the status showing "PayPal Processing" until you manually update it to something else or delete it, because the program doesn't get any feedback from PayPal and thinks that the person is still in the process of making a payment.
